S8.C.3.1 Describe the effect of multiple forces on the movement, speed, or direction of an object.
S8.C.3.1.1 Describe forces acting on objects (e.g., friction, gravity, balanced versus unbalanced).
S8.C.3.1.2 Distinguish between kinetic and potential energy.
S8.C.3.1.3 Explain that mechanical advantage helps to do work (physics) by either changing a force or changing the direction of the applied force (e.g., simple machines, hydraulic systems).
Design or evaluate simple technological or natural systems that incorporate the principles of force and motion (e.g., simple machines, compound machines).
Calculate the mechanical advantage for moving an object by using a simple machine.
Identify elements of simple machines in compound machines.
